Display panel and preparation method for the same, and evaporation device

A display panel, comprising:

• a substrate;
• an isolation structure, located on a side of the substrate, and comprising a crown and a support portion that are arranged in a stacked manner, the crown being located on a side of the support portion away from the substrate, and an orthographic projection of the support portion on the substrate being within that of the crown on the substrate;
• and at least one light-emitting unit, located on the same side of the substrate as the isolation structure, and comprising a first functional layer, wherein
• the display panel has a plurality of cutting planes that pass through a center of the light-emitting unit and are perpendicular to a plane in which the substrate is located, wherein in any one of the cutting planes, an included angle between a first straight line determined by an edge of a side of the support portion close to the substrate and an edge of the crown and the plane in which the substrate is located is a third included angle, and an included angle between a second straight line determined by an edge of the first functional layer and the edge of the crown and the plane in which the substrate is located is a fourth included angle, the fourth included angle being greater than the third included angle.

A preparation method for a display panel, comprising steps of:

• providing a substrate;
• preparing a support portion on a side of the substrate;
• preparing a crown on a side of the support portion away from the substrate, wherein an orthographic projection of the support portion on the substrate is within that of the crown on the substrate;
• and
• preparing at least one light-emitting unit on the same side of the substrate, wherein the light-emitting unit comprises a first functional layer, and the first functional layer extends toward the support portion,
• wherein the display panel has a plurality of cutting planes that pass through a center of the light-emitting unit and are perpendicular to a plane in which the substrate is located, wherein in any one of the cutting planes, an included angle between a first straight line determined by an edge of a side of the support portion close to the substrate and an edge of the crown and the plane in which the substrate is located is a third included angle, and an included angle between a second straight line determined by an edge of the first functional layer and the edge of the crown and the plane in which the substrate is located is a fourth included angle, the fourth included angle being greater than the third included angle.
